Grams to moles to atoms
(41.6)g/(1 )×(1mol)/(87)g×(6.022×10^23)atoms/(1mol)
the 87 comes from the periodic table Sr has 87 as atomic weight
grams cancel then moles cancel and you are left with atoms
=2.87×10^23atoms
with all numbers it is 2.8794851×10^23atoms
Answer:
It is not "strong acids have a low pH"
Explanation:
I feel it should because that is a true statement but for Primavera it is wrong.
<span>They have similar or common ancestor. The similarities inherited from the common ancestor as in the case of homologous organs. In evolutionary biology a group of organisms share a common descent if they have a common ancestor. There are many other examples like in the case of hemoglobin to prove the theory of common ancestor</span>
Well you use the atomic mass of helium and multiply by the 3.75 grams. Then you will get the answer around 3.7875
